* libtiff/tiffiop.h, tif_aux.c: redirect SeekOK() macro to a _TIFFSeekoK()

function that checks if the offset is not bigger than INT64_MAX, so as
to avoid a -1 error return code of TIFFSeekFile() to match a required
seek to UINT64_MAX/-1.
Fixes http://bugzilla.maptools.org/show_bug.cgi?id=2726
Adapted from proposal by Nicolas Ruff.
